Common Error Codes & System Events
- Event ID: 10000
- Communication error between HMI panel and PLC controller. Connection to the configured controller cannot be established or has been lost.
Check PROFIBUS or Ethernet cable connections and termination resistors. Verify PLC address settings match the HMI project configuration. Restart both the HMI and PLC if necessary. - Event ID: 10001
- Tag read error. The HMI panel is unable to read a configured tag from the controller.
Verify the tag address in WinCC flexible matches the actual PLC data block or memory address. Check that the PLC program is running and the relevant data areas are accessible. - Event ID: 10002
- Tag write error. A write operation to a controller tag has failed.
Check that the target PLC memory area is not write-protected. Verify tag addressing in the HMI project and confirm the PLC is in RUN mode. - Event ID: 20000
- Project loading error. The HMI runtime was unable to load the project file from storage.
Check the CompactFlash card for errors or corruption. Re-transfer the project from WinCC flexible engineering software. Ensure the project was compiled without errors before transfer. - Event ID: 40000
- System memory low. Available runtime memory is critically low, which may affect panel performance.
Reduce the number of active screens or tags in the project. Archive or delete unnecessary log files and alarm records stored on the panel. - Event ID: 50000
- Backup battery low or missing. The internal backup battery voltage is below the required threshold.
Replace the internal backup battery with the correct Siemens replacement part. Refer to the MP 377 operating instructions for battery replacement procedure. - Event ID: 70000
- Screen saver or display fault. The display backlight has failed or the screen saver has activated unexpectedly.
Check the screen saver settings in the panel configuration. If the backlight has failed, the display unit or backlight inverter may require replacement. - Event ID: 80000
- USB device error. A connected USB device is not recognized or has caused a communication fault.
Disconnect and reconnect the USB device. Ensure the USB device is compatible with Windows CE 6.0. Avoid using USB hubs unless confirmed compatible with the panel.
Frequently Asked Questions
What runtime software does the SIMATIC MP 377 15" Touch use?
The MP 377 runs WinCC flexible Runtime under Windows CE 6.0. Projects are engineered using WinCC flexible on a PC and transferred to the panel via Ethernet, USB, or CompactFlash card.
Which communication interfaces are available on the 6AV6146-4MM40-0KY2?
The panel provides a PROFIBUS DP interface, a PROFINET/Ethernet RJ45 port, two USB 2.0 ports, and a CompactFlash card slot. This allows connectivity to both SIMATIC S7 PLCs and third-party controllers.
Is the MP 377 compatible with SIMATIC S7-300 and S7-400 PLCs?
Yes, the MP 377 supports direct communication with SIMATIC S7-300 and S7-400 controllers via PROFIBUS DP or PROFINET/Ethernet, and is fully configurable using WinCC flexible engineering software.
What is the supply voltage for the 6AV6146-4MM40-0KY2?
The panel requires a 24 V DC supply voltage. Ensure the power supply can deliver sufficient current to meet the panel's maximum power consumption of 50 W.
Can the MP 377 be used with third-party PLCs?
Yes, the MP 377 supports communication drivers for various third-party controllers through WinCC flexible, including Allen-Bradley, Mitsubishi, and Modbus-compatible devices, in addition to Siemens SIMATIC systems.
Troubleshooting
Display remains blank after power on
Measure the 24 V DC supply voltage at the panel's power connector. Check that the supply polarity is correct and that the voltage is within the specified range. Inspect the internal fuse if accessible.
Correct any supply voltage issues. If the supply is confirmed good and the display remains blank, the backlight or internal power supply board may have failed and the panel should be sent for repair or the backlight unit replaced.
Touchscreen does not respond or registers incorrect touch positions
Check whether the touch issue is consistent across the entire screen or limited to specific areas. Attempt a touchscreen recalibration from the Windows CE control panel or the SIMATIC HMI startup menu.
Perform a touchscreen calibration using the built-in calibration tool. If calibration does not resolve the issue, the resistive touch overlay may be damaged or worn and requires replacement.
HMI project fails to transfer from WinCC flexible engineering PC
Verify the Ethernet or USB connection between the PC and the panel. Confirm the panel IP address matches the transfer settings in WinCC flexible. Check that the panel is in transfer mode.
Set the panel to transfer mode via the Start Center menu. Ensure the PC and panel are on the same network subnet if using Ethernet transfer. Disable PC firewall temporarily to rule out connection blocking.
Panel repeatedly reboots or freezes during runtime
Check for low memory warnings in the system event log. Inspect the CompactFlash card for errors using a card reader on a PC. Verify the project does not exceed the panel's memory or tag count limits.
Optimize the WinCC flexible project to reduce memory usage. Replace the CompactFlash card if errors are detected. If the issue persists, perform a factory reset and re-transfer the project.
PROFIBUS communication fault displayed at runtime
Check the PROFIBUS cable connections, termination resistors at both ends of the bus, and the bus address configured on the panel. Use a PROFIBUS diagnostic tool to check bus signal quality.
Correct any wiring faults and ensure termination resistors are only fitted at the two physical ends of the PROFIBUS segment. Verify the panel's PROFIBUS address in the WinCC flexible project matches the hardware setting.
